SPECIFICATION forming part of Letters Patent No. 255,61*?, datedvMarch 2B, 1882.

Application filed January 25, 1882.

To all lv/tom it may concern: t

Be it known that I, JAMES F. J. GUNNING, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Sewing-Machine Guides; and l do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description ofthe same, and which said drawings constitute part of this speciticatiomand represent, in-

Figure 1, a top or plan view; Fig. 2, a longituditudinal central section; Fig. 3, a top View with the cap removed; Fig. 4, a section of work to illustrate the operation of' the guide.

This invention relates to an improvement in guides for sewing-'machines, with special refer ence to that class which are used in making pockets in fabrics, such as required in corsets for the insertion of the bones or stays, a section of which is seen in Fig. 4, in which a represents the first pocket, and b the second. These pockets are made by parallel lines ot' stitches run through two fabrics, d e, alld as atfg. It these stitches be run through the 'two fabrics while perfectly flat, it is difficult to opell the pockets for the insertion of bones, whereas if the pockets be formed overa tonguelike guide, then the insertion ofthe stays is a simple and easy matter.

Guides have been made with tongues over which the pockets have been formedthat is, one thickness separated from the other by the tongue; butin such guides the tongue is of a constant width or invariable, and whenever a dil'erent width of such pocket is required a different guide must be applied to the machine. It frequently occurs that numerous widths of such pockets are desirable, or that parallel lines of stitches through fabrics at varying distances are required. t

llhe object of my invention is to lnakea guide readily adjustable to different widths or distances between the parallel lines of stitches; and it consists in asegment-shaped tongue arranged to rotate around a center, whereby the lines of stitches, when a. tangent ot' that segment, will be distant the width of the segment, the width of the pocket being increased as the end of the segment is turned around or brought (No model.)

nearer the needle, as more fully hereinafter described. v

A represents the arm by which the guide is secured to the work-plate, the arm being provided with a slot, B, through which a screw may be inserted to Vsecure the guide. The working end of the guide is preferably made circular in shape, h being the center. Onto this circular part a segment-shaped tongue, C, is arranged, so that it may be rotated thereon, with the center h as its cellter of motion.

The tongue C is here representedas nearly a complete ring,.and lies upon the under plate, D, with a plate, E, within it and tired to the under plate, of substantially the same thickness as the tongue, then a cap, F, covering it, so that the segment-shaped tongue may be rotated in its seat, the center 7L being the center of rotation; or the guide can be arranged in any suitable groove or bearing, so as to be thus rotated. The width of the tongue C at its working end t' is that of the inarrowestpocket or space between the parallel lines ot' stitches required. One thickness of fabric passes below the tongue alld the other above, as seen in Fig. 4. Suppose the tongue or guide to be set to the position seen in Fig. l, and so that the line of stitches m to be made is a tangent from the inside of the tongue alid the lille of stitches n last made a tangentl'rom the outside of the end of the tongue. Then the width ofthe tongue indicates the space between thc two lilies ot' stitchesthat is, as seen in Fig. 4. The one lille ot' stitchesfis brought against the outside of the tongue, and the new lineot stitches against the inside, or as near as may be, r indicating the position of the needle in making stitches. lll this arrangement the two thicknesses of fabric with theline ofstitches therein willrun offthe tongue in the usual manner for other tongue-guides. Now suppose a broader space is required between the lines of stitches, such as indicated by the lines m rn,Fig. 3. The tongueCis turned forward until the inner edge of the end is distant from the tangenta equal to the width re-V IOO a 25Min Thus the width between the two lines m n will be increased to the extent to which the segment-shaped tongue may have been turned.

The tongue isolamped in position and may be set by a binding-screw, s, which clamps the cap hard down upon it with sufficient force to hold it in place.

vTo insure a direct line Vot' stitches I apply a second tongue, H, which extends outward between the two thicknesses of fabric, as seen in Fig. 4. This is arranged between the lower plate and cap in suitable guides, so as to move back and forth toward the tongue, as from the outward position, Fig. l, to the inner position, Fig. 3. It is secured to the plates at any position to which it may be desired by the screw t, or other suitable device, so that the edge ot' the tongue will run against the line of stitches being made between the fabrics. Hence the path of the work will be governed by that line of stitches being made as it runs against the end 1'- of the tongue around one side and the second tongue H on the other side. lf these be in a straight line, then the work will be in acorrespondingly straightline; butit'the work is to be curved, then the tongue H will be moved outward or inward, according as the curve is to be to the right or left. This tongue may be made to slide betweenv thecap and under plate, as here represented; or it may be a part of the central plate, E, and turn upon the same center toward or from the tongue.

The adjusting-tongue H may be employed with a stationary tongue-that is to say, for illustration, suppose the tongue G in the drawings to be stationary, the tongue H, adjustable thereto, will govern the path of the work, so that thelines be straight or curved, as hereinbefore described. Hence I do not wish to limit the use of the guide H to the rotating tongue.

I claim- 1. The herein -described sewing machine guide, consisting of the segment-shaped tongue C, arranged upon its holder so as to bc rotated thereon, with its end t' to lie between the thicki ncsses of fabric to be stitched together, substantially as described.

2. The herein-described sewing-machine guide, consisting ot' thesegment-shaped tongue C, arranged upon its holder so as to be rotated thereon, with its ende' to lie between the thicknesses of fabric to be stitched together, combined with an adjustable tongue, H, substantially as described.

3. In a sewing-machine guide, the combination of a tongue arranged to lie between the twothicknesses offabricto be stitched together, and an adjustable tongue arranged to bear between the fabrics against the line of stitches being made, while the other tongue lies upon the opposite side of said line ot stitches, substantially as described.
